  • Abstract
    The initial stages of electrical breakdown of atmospheric air have been captured with a fast-framing camera. The peak voltage is 100 kV with a duration of 60 ns and is applied to a 4.6-cm gap. The camera captures the start of the positive column, the initial cathode spot, and the development by ionization waves into a hot channel.
